Lecture 2 - Design Methodologies for Mechatronic Systems Design

Introduction

• VDI 2206
• Medicine components = system components -> solving the problem
• Modules synergy

Examples

• ABS

Components

• Control can be of different types (mechanical, logic gates, FPGA), not necessarily an MCU

Philosophy

• Concurrent
• Synergy (systems engineer) -> Requirements satisfaction
• Design considerations
  • Plug and Play
  • Integration
  • Assembly
  • Disassembly and Maintenance
  • Interfaces
  • Connectors
  • Manufacturing
• Features development and extensibility
• Efficiency
  • Cost
  • ...

Design Methodologies

• Mechatronic System structure

Problem-solving cycle

• Macro: Phases of Mechatronic Systems Design Process
  • Requirements
    • Technical & Non-technical
  • System Design (conceptual design, (functional) block diagram)
  • Domain specific design (detailed design) = Modelling and simulation
    • MiL (simulation block diagrams)
    • SiL ()
    • HiL (hardware controller)
  • System integration (high weight)
    • Distributed components
    • Modular
    • Spatial
  • Assurance (validation and verification)
    • verification -> technical requirements satisfied
    • validation -> product satisfies needs
• Micro: Problem-solving cycle as a micro-cycle (quick brainstorming)
